CL57-R Bus Closed-Loop Stepper Driver

Product Overview

The CL57-R stepper driver adopts the new generation 32-bit DSP technology, combined with RS485 bus control functionality, supporting the MODBUS-RTU communication protocol. It can connect up to 32 axes and achieve multi-axis bus synchronous control. The driver features 15 internal position segments and 15 internal speed segments, supports automatic homing, absolute/relative positioning, JOG functions, and can be directly controlled using a touchscreen or a controller with an RS485 interface.

Features

Voltage input range: DC24V~50V Maximum peak current: 5A Communication interface: RS485 Communication protocol: Modbus RTU Encoder: 1000-line incremental Automatic motor parameter tuning function Protection functions including overvoltage, overcurrent, and position deviation alarms
